Troubleshooting Receiver will not turn on: 1. Check to see if batteries are installed correctly. 2. Replace with two new AA alkaline or lithium batteries. Takes more than 10 minutes to get a position fix: 1. If there are any obstacles nearby or overhead, move to a new location. 2. Make sure that the antenna is pointing up, has a clear view of the sky and is a reasonable distance away from your body. 3. Check Satellite Status to see where the satellites are and if the receiver is acquiring data. 4. If the receiver still does not get a position fix within 10 minutes, you may wish to repeat the initialization procedure. Elevation jumps up and down: 1. Errors induced by the Department of Defense called Selective Availability (SA) can cause the elevation values to fluctuate. Battery life seems shorter than it should be: 1. Make sure that you are using two AA alkaline or lithium batteries. 2. Shorter life span of the batteries can be due to excessive use of the backlight. Turn the backlight off when not needed. Position coordinates on your receiver do not match the location on your map. 1. Make sure that your receiver is set up to use the same datum as your map. The map datum is generally shown in the map legend. See Map Datum under Reference for instructions on selecting the map datum in your receiver. 2. Check your LAT/LON format. Make sure that the format selected in COORDINATE SYSTEM (DEG/MIN/SEC or DEG/MIN.MM) is in the same format as the map you are using. Magellan GPS 315/GPS 320 49

4.
If the receiver still does not get a position fix within 10 minutes,
you may wish to repeat the initialization procedure.
Elevation jumps up and down:
1.
Errors induced by the Department of Defense called Selective
Availability (SA) can cause the elevation values to fluctuate.
Battery life seems shorter than it should be:
1.
Make sure that you are using two AA alkaline or lithium
batteries.
2.
Shorter life span of the batteries can be due to excessive use of
the backlight.
Turn the backlight off when not needed.
Position coordinates on your receiver do not match the location on
your map.
1.
Make sure that your receiver is set up to use the same datum as
your map.
The map datum is generally shown in the map
legend.
See
Map Datum
under
Reference
for instructions on
selecting the map datum in your receiver.
2.
Check your LAT/LON format.
Make sure that the format
selected in COORDINATE SYSTEM (DEG/MIN/SEC or
DEG/MIN.MM) is in the same format as the map you are
using.
